I really dont care to put that much effort into it. But I doubt for $35 you're getting a fully moldable stiff insole. And they have to be fully moldable to go from that flattish shape to full supportive.

So i gotta say i was one of the doubters too when i first came across these but to be fair i just sucked it up and bought a pair of these just to try out. Im not sure about using them for snowboarding since i have no experience using them with snowboard boots.

But for day to day use, god damn you notice a difference. Its like night and day.
Imagine walking on a hard wood floor, and then switching over to a fresh new carpet with a thick lining under it.

I have played football (soccer for those across the pond) on astro which normally knackers my feet and heels, these seriously make a hell of a difference, seriously noticable difference. I switch the one pair between all my shoes now every day without fail.

Can i compare them to footbeds? No since i bought the flat ones just for daily shoe use but to my knowledge you can get custom orthotics with support around the heel and custom moldable arch support. I'm mighty tempted but want to see if people think that these will work for snowboarding before taking the plunge. Especially since i bought with international shipping so when my first pair work so well im kinda hesitant for a second pair. When i bought them i did so because i do a hell of a lot of running and walking and my soles on my shoes would wear out super fast.

Also saw some other kid on the internet testing the kingfoam soles, then dropping the egg immediately after and it cracked like the rest of em.

Sad as it may seem in the first week i found myself just jumping around in them testing them cos they were that comfy...

I'd say if someone in the US is curious enough then theres no reason not to, cant guarantee they'll be good for snowboarding since its not what theyre made for but maybe it would be worth suggesting it to them to consider in the future

I bought a set of the "game changer" insoles from them almost a year ago. At the time they had a promotion for a free pair of the kingfoam flat insoles as well. The game changer ones I have came with a needle that youd use to inject water into the insole, which made them puff up and then mold to your foot when they hardened (about 15min). The new model appears to be heat activated instead of water so I dunno if theyd be comparable.

Long story short I ended up starting a new job and never got a chance to buy some new boots and actually get on the hill. That being said I've recent bought a pair of boots and have finally molded the insoles. I've still yet to get up the hill but from test fitting them around my house they are extremely comfortable. My entire foot is supported and they do feel like theyd absorb quite a bit of shock.

As for the flat kingfoam ones. I normally wear my street shoes and work boots big 10-10.5 and the size 9's I got for my snowboard boots dont even come close to fitting in my shoes.

I don't really have any real world experience with them yet but what I can tell you is that I do buy into the hype. The foam these use is 100% different then any insole I've ever felt and it does feel like it would absorb impact rather then reflect it unlike your typical gel padding...

They also have a satisfaction guarantee. So far I like them better then the sole and superfeet insoles ive owned.
